Description

This application generates International Space Station (ISS) Transit Predictions for the Sun, Moon and Planets.

The user specifies a location, which includes latitude, longitude and elevation. The application downloads the latest orbital information (Two Line Elements or TLEs). The application generates a transit prediction map which contains prediction paths for each transit within a specified alert radius.

LOCATIONSAdd a named observing location by clicking the "Location" button accessible from the main screen.

The location coordinates can be entered in any of three methods:•Manually - Enter latitude, longitude and elevation in the text boxes. Positive values represent North and East, negative values South and West. Elevation can be entered in meters or feet above sea level depending on the current prediction units setting. As the coordinates are typed, the map pans to the location. Press the search button to search for a location.•Map Input - Use the map to zoom and pan to a location. Pressing the Set button sets the location name, coordinates and elevation in the text boxes. The elevation of the current coordinates is retrieved using the specified elevation data source setting. Switch between map and satellite modes by toggling the Map/Sat button.•GPS - By pressing the GPS button, the application uses GPS to obtain location coordinates and elevation.Use the locations page accessible from the options menu to edit and delete saved locations.

GENERATING PREDICTIONSOnce a location has been entered and TLE have been downloaded, press the "Generate Prediction" button to begin prediction generation. The progress bar gives an indication of how long it will take to complete the process. Depending on your CPU speed, it can take a few minutes to generate the predictions. Pressing the cancel button will cancel the prediction.

VIEWING PREDICTIONSOnce the prediction generation is complete, the prediction map or text file can be viewed. Pressing the View Prediction button brings up the previously generated prediction map. The text button within the map view displays the prediction text. The Map/Sat button switches between Map mode and Satellite mode.

Within the map view press the Google Earth button to view the map in Google Earth (Pro Version Only). Press the save button to save the prediction for later viewing (Pro Version Only).Use the predictions page accessible from the options menu to view, share and delete previously saved prediction maps (Pro Version Only).

Skip this one Ads on the bottom and constant full screen ads popping up every step of the way. Deceptive or maybe too small close buttons interrupt the generation of predictions. No thanks, I'd pay the buck to get the pro version, but you've lost my trust on the bombardment of ads you've allowed. Once again the almighty dollar takes center stage over a working app.

Accurate and easy to use! I used this to plan my very first ISS solar transit and it worked perfectly, got some amazing shots. It's very easy to use, and will find any transit within 100 miles and 11 days. Author was very helpful and answered all my questions.
